Based on the idea of virtual synchronous machine, a control strategy of traction rectifier is proposed. The proposed strategy provides the voltage and frequency support for the traction grid, damps oscillation, which helps to improve the stability of the power system. In this way, the electrical energy can be fed back to the traction grid more friendly in the regenerative braking condition. The experiment proves that the control strategy has good control effect both on traction and regeneration braking conditions.
